Expanding foam has its place, but it is not airtight. If you want to reduce heat loss around windows and doors, you need air seal tape along with cavity closers for a best practice installation.

Disruption plays a key role in deciding which measures are appropriate to an occupant or to their property. This article was written for Detail Library and explores how designers and retrofit professionals can minimise disruption for our clients.

This extract from an article I wrote for Detail Library explores the common measures that take place alongside a heat pump installation to help achieve a successful outcome, good levels of comfort and low bills.

Extract from a full article I wrote for Detail Library covering the importance of understanding the existing fabric of a building before matching appropriate retrofit measures.

Abbreviated version of an article I wrote for Detail Library covering the history of PAS 2035 and the effects of the most recent update on the key retrofit roles and the process itself.

Chapter 2 Architects are now listed on the Retrofit West Trusted Professionals Directory. Being part of Retrofit West shows our commitment to providing you with the best possible home retrofit experience.

Professional titles can sometimes be confusing. Three (or more) letter acronyms and abbreviations that may confuse rather than reassure. For my sins, I’ve gathered quite a few now, so let me explain what they mean for those who are unsure.

April is the month when solar production begins to outstrip what we use at home, meaning we start to get paid for the energy we export back to the grid.

Pulse Tests are carried out by specialist air testing companies as a quicker alternative to Blower Door testing, particularly for existing buildings undergoing retrofit or older buildings.

As we celebrate our first anniversary, here are 10 retrofit lessons from (just) one year.

EnerPHit is where Retrofit meets Passivhaus. This blog explains some of the key differences and routes to certification for those who do not want to move to achieve their dream energy efficient home.

New service - Thermographic Imaging Report for diagnosis of heat loss and air leakage, plus solutions!

What is a Watt? What is kWh? It depends on who you ask. Try comparing one building to another and you could quickly become unstuck. Let’s take a myth-busting dive into the standard metric for building energy use.

Bath & NE Somerset’s pioneering net zero carbon planning policy has been studied by a group at University of Bath with external partners Chapter 2 Architects and the South West Net Zero Hub.

If I had to explain retrofit to someone in 2mins I’d whip out this diagram.

Energy efficiency comes from optimising your design. Adding insulation increases performance but past a certain point it only adds more cost with little additional benefit. This is the law of diminishing returns.

Form Factor and orientation play a huge role in the eventual heat loss characteristics of your building. Simplifying the form and using design tools can help you optimise your form, and reduce your heat loss.

A brief explainer on the role of Retrofit in addressing the UK’s 2050 climate commitments, covering the role of designers, PAS2035 and recognised methodologies from LETI, RIBA, Passivhaus and AECB.

Using an inexpensive indoor air quality meter to asses the health of our home, looking at carbon dioxide, relative humidity and temperature as we work from home, or rest.

PHPP is the tool developed by the Passive House Institute to achieve compliance with their standard. It is used by Passive House Designers and Certifiers to evaluate designs through the project life, but can have wider applications.
